Regular expression to get text between square brackets including disparity?

Question

I need to find a regular expression for use in C# (JavaScript as well), for get the text inside the either square brackets combination.

I try several ways, but I give up

Answer 1

This matches everything except square brackets: [^\[\]]+

This captures anything that is not a square bracket between any number of open (LHS) and close (RHS) square brackets:

\[+([^\[\]]+)\]+

Example usage in Javascript:

'[[[[[test]]]]'.match(/\[+([^\[\]]+)\]+/)
> ["[[[[[test]]]]", "test"]

The regex tester at http://regexpal.com/ is useful for trying out regexes.
